Abstract

a presente invenção refere-se a uma estrutura de vedação de extremidade de rampa de alimentação de combustível para motor de injeção direta de gasolina que apresenta uma estrutura simples e que permite que uma parte da tampa de extremidade atenda os requisitos de pressão mais alta em uma rampa de alimentação de combustível apresentando a estrutura na qual uma extremidade ou ambas as extremidades do corpo de uma rampa composto de um membro tubular, tal como um tubo, são fechadas por uma tampa de extremidade ou tampas de extremidade. a estrutura de vedação de extremidade emprega um método de fixação de rosca que usa a tampa de extremidade e um colar brasado na extremidade de abertura do corpo da rampa de alimentação de combustível e um método de vedação de gaxeta como um método de vedação, onde uma gaxeta interposta entre a tampa de extremidade e o corpo da rampa de alimentação de combustível é apertada por meio de uma força axial gerada devido ao aperto da tampa de extremidade que é atarraxada e fixada no corpo da rampa de alimentação de combustível de modo a ser vedada.The present invention relates to a direct fuel injection engine fuel ramp end sealing structure which has a simple structure and allows a portion of the end cap to meet the highest pressure requirements in a A fuel feed ramp having the structure in which one end or both ends of the body of a ramp composed of a tubular member, such as a pipe, is closed by an end cap or end caps. the end sealing structure employs a thread clamping method that uses the end cap and a brazed collar at the opening end of the fuel feed ramp body and a gasket sealing method as a sealing method where a gasket interposed between the end cap and the fuel feed ramp body is tightened by an axial force generated due to the tightening of the end cap which is screwed and secured to the fuel feed ramp body to be sealed .
